you can probably find a carb setup for around that much, but i think you'll need a new upper intake manifold and fuel pump (and lines?).

if all you have is $400 then you might as well sell it.

You'll need at the minimum, new carb and intake manifold, new exhaust, new fuel system, 12a-13b adapter (unless you wanna slot your 12a mounts, but I wouldnt do that), egr block off plate. I think thats it, but thats gonna run you more than 400 bucks man.

I only said that because I have access to everything I'd need to drop an FC engine into a 1st gen.

GSL-SE oil pan, '74-'85 front cover (GSL-SE if you need all four OMP lines), RB front cover mount to fit a 13B into a 12A chassis, 13B cast iron manifold or a header, stock lower intake manifold, Racing Beat upper manifold with a Weber or dellorto carb, or RB's Holley manifold and RB modded Holley carb, oh man, the list goes on.

Well, whatever you do, we'll be here. Are you going to port the 12A?

my 12a has no compression at the moment, no lost seals, so a rebiuld is in order
